WS #16055

The S&P 500 closed the week down 1.09%, caught in a structural divergence where broad indices fell while 247 of 494 heavyweights actually rose. The primary headwinds are a resurgence of geopolitical risk—Brent crude surging past $110 on Strait of Hormuz threats—and a renewed AI credit crunch, epitomized by CoreWeave's 12% plunge. This dual pressure has triggered a rotation out of high-multiple tech and into defensive energy and value plays, with Targa Resources leading the heavyweights higher while Super Micro Computer collapsed nearly 10%. The energy sector is experiencing a violent repricing as the geopolitical narrative shifts from localized conflict to global supply chokepoints. The closure of the Strait of Hormuz has shelved 15 million barrels of marketable oil, driving a sharp spike in crude prices that is simultaneously boosting energy equities and crushing airline margins. Concurrently, the semiconductor complex is facing a liquidity crisis; the Semiconductor ETF has hit its longest losing streak since 2006, and CoreWeave's financing fears are reverberating across the AI infrastructure stack. Despite this, Apple is emerging as a standout performer, supported by strong iPhone Duo demand and a recent patent victory, decoupling it from the broader AI sell-off. Secondary themes include a tightening labor market for US tech firms due to H-1B crackdowns and a notable institutional accumulation in large-cap ETFs, evidenced by a $537 million dark pool block in the S&P 500 ETF (IVV). The market is pricing in a 'higher for longer' inflation environment driven by energy, which is forcing central banks like the RBI to raise inflation forecasts, adding macro headwinds to the equity selloff.
